Idk how class works

I'm working with creating the functions in a separate file, so I wanted to create a function that would ask for a phrase and save it as a string, and call it from my "main" to work with that, but I don't know what I'm doing wrong exactly.

Have you tried reading the errors?

3333fred Have you tried reading the errors?

AriieSiiSOP•1/17/23, 6:59 PM

Yes but I don't understand what it means, I get "not all paths return a value".

AriieSiiSOP•1/17/23, 6:59 PM

and in the first one

333fred•1/17/23, 6:59 PM

You aren't returnreturning anything

Angius•1/17/23, 7:00 PM

If a method has a return type that isn't voidvoid, it needs to return something of that type

Angius•1/17/23, 7:00 PM

Simple

AriieSiiSOP•1/17/23, 7:00 PM

ok, i am stupid and forgot that

AriieSiiSOP•1/17/23, 7:00 PM

fixed the error

AriieSiiSOP•1/17/23, 7:00 PM

but i still got one in the first screenshot

333fred•1/17/23, 7:01 PM

And what does that error say?

AriieSiiSOP•1/17/23, 7:01 PM

can't convert the method group "PedirFrase" to the non-delegated type "string" did you try to call the method?

Angius•1/17/23, 7:01 PM

You need to call that method

Angius•1/17/23, 7:01 PM

Not just state its name

AriieSiiSOP•1/17/23, 7:02 PM

and how i do it?

Angius•1/17/23, 7:02 PM

Like with any other method call

Angius•1/17/23, 7:02 PM

There's 6 method calls in your code already, so you should know how to do it

AriieSiiSOP•1/17/23, 7:02 PM

writing () ?

AriieSiiSOP•1/17/23, 7:03 PM

I've tried it and that's what it is, although I don't really understand it at all.

AriieSiiSOP•1/17/23, 7:03 PM

i.e. I didn't know that to do so I had to put () obligatorily

AriieSiiSOP•1/17/23, 7:03 PM

but ty

AriieSiiSOP•1/17/23, 7:03 PM

sorry for my noob questions

AriieSiiSOP•1/17/23, 7:04 PM

trying to understand things

AAngius Like with any other method call

AriieSiiSOP•1/17/23, 7:17 PM

AriieSiiSOP•1/17/23, 7:17 PM

in VerFrase() how can i refeer to the string i made in the first one

Angius•1/17/23, 7:17 PM

$scopes

AAngius $scopes

MODiX•1/17/23, 7:17 PM

scope A {
  thing a;
  scope B {
    thing b;
  }
}

scope A {
  thing a;
  scope B {
    thing b;
  }
}

thing athing a is available in scope Ascope A and scope Bscope B
thing bthing b is available only in scope Bscope B

Angius•1/17/23, 7:18 PM

frasefrase exists only in PedirFrase()PedirFrase() method

AriieSiiSOP•1/17/23, 7:18 PM

Ok, so to see it I should store it in another variable?

AriieSiiSOP•1/17/23, 7:18 PM

so i can use it with the others funcionts

Angius•1/17/23, 7:18 PM

You could call this method, and use what it returns

Angius•1/17/23, 7:18 PM

The same way you use what Console.ReadLine()Console.ReadLine() returns

AAngius You could call this method, and use what it returns

AriieSiiSOP•1/17/23, 7:19 PM

Yes, but I already call it in the main, so when I call it again it asks me to write the string again, and I want to continue working with the string I picked up the first time.

Angius•1/17/23, 7:19 PM

Well, you can make VerFrase()VerFrase() take a string

Angius•1/17/23, 7:20 PM

Then you would get the string in the main, and then you'd pass it to VerFrase()VerFrase(), also in the main

AAngius Well, you can make `VerFrase()` take a string

AriieSiiSOP•1/17/23, 7:21 PM

I don't understand what you mean here sorry

333fred•1/17/23, 7:21 PM

Are you familiar with parameters?

Angius•1/17/23, 7:22 PM

Console.WriteLine()Console.WriteLine() takes a string as a parameter

Angius•1/17/23, 7:22 PM

Your method can, similarly, take some parameters

333fred•1/17/23, 7:22 PM

~~Did you mean WriteLine?~~

3333fred Are you familiar with parameters?

AriieSiiSOP•1/17/23, 7:25 PM

not too much, i mean probably yes, but I don't know, until today I had only worked on the "main" doing exercises, so I'm getting a bit confused with the whole topic of functions, methods, calls, etc.

AriieSiiSOP•1/17/23, 7:26 PM

but I think I know what you are saying

333fred•1/17/23, 7:26 PM

I would suggest going through $helloworld, which will introduce you to these concepts

VerFrase(frase)

AriieSiiSOP•1/17/23, 7:27 PM

right?
